What Is Reactoonz?
Reactoonz by Play'n GO is a 7x7 grid cluster-pays slot that became one of Play'n GO's most distinctive and popular releases when it launched in 2017. Its alien creature characters, fluctuating charge meter and four distinct special features tied to that meter give it a mechanical depth that set a new standard for grid slots.
The Quantumeter is the heart of Reactoonz. This charge meter fills with each winning tumble, unlocking one of four special features — Implosion, Alteration, Demolition and Incision — at successive threshold levels. The combination of these features and the rare one-eyed Gargantoon wild creates a slot with more base-game variety than almost any contemporary.
RTP & Volatility
Reactoonz carries a published RTP of 96.51%. High volatility means wins are less frequent but can be significantly larger when they land, rewarding patience.
RTP is a theoretical long-run figure — it does not predict outcomes in any single session. Set a budget before playing.
Key Features
Each Quantumeter charge level triggers a different feature: Implosion converts a cluster of symbols into wilds; Alteration transforms all instances of one random low-pay symbol into another; Demolition destroys all low-pay symbols from the grid; and Incision shoots a 3x3 wild across the reels. These features can chain in a single spin sequence.
The Gargantoon wild is a 3x3 giant symbol that appears when the Quantumeter is fully charged. Each tumble shrinks it by one — from 3x3 to 2x2 to 1x1 — and each size applies its substitution power to the shrunk footprint. A 3x3 Gargantoon can persist across multiple tumbles, contributing to multiple consecutive wins.
Winning clusters of five or more matching symbols destroy all adjacent symbols in addition to the winning cluster, extending the board clearance. The tumble mechanic replaces removed symbols from above, allowing chain wins from one paid spin. The combination of Quantumeter features, Gargantoon and cluster-clear creates a slot where every spin can escalate dramatically.
Theme & Design
Alien creatures called Reactoonz populate the 7x7 grid in vivid cartoon colours — green cyclops aliens, purple four-eyed creatures, orange star-shaped beings and more. The design is playful and distinctive, unlike any other slot aesthetic. The electronic sound effects and responsive animations give the game an energetic, gaming-culture feel.
Verdict
Reactoonz remains one of Play'n GO's finest achievements. The 96.51% RTP is solid, the Quantumeter creates persistent engagement across every spin, and the depth of interaction between its features is genuinely impressive. For Irish players who enjoy mechanically rich grid slots, Reactoonz is essential.
